  Common elimination guide for screw air compressor
In order to guide and solve the failure of the unit in time, we make up the working condition of the daily work.
The guide is made. The possible reasons for the failure are listed in this guide, but not all of them. I hope you will constantly provide us with new discoveries and methods in the process of use, so that we can continuously improve this guide and make it an effective tool for us.
Fault phenomenon: the exhaust temperature of the unit is high (over 100. degrees C)
1The coolant level of the 1 unit is too low (it should be seen from the oil peep, but not more than half)
2 oil cooler dirty
3 oil filter core blockage
4 temperature control valve failure (original part)
5 fault oil solenoid valve failure
6 cooling fan failure
7 Unblocked or exhaust resistance (large back pressure) of row air duct
8 temperature sensor failure
Failure phenomenon: large oil consumption or high oil content in compressed air
1 too much cooling dose
2 back tubing blockage
The installation of the 3 tubing (the distance to the bottom of the oil separation core) does not meet the requirements.
The pressure of the 4 unit is too low
Rupture of 5 oil separation core
Oil leakage of the 6 unit
7 modified or overdue use of coolant
Failure phenomenon: low unit pressure
1 the actual gas consumption is greater than the gas output of the unit
2 vent valve failure (can not be closed when loading)
3 inlet valve failure hydraulic cylinder failure pressure setting is too low
4 load solenoid valve (ISV) failure pressure valve card death
Fault phenomenon: the large current of the unit
1 the voltage is too low
2 connection loosening
Pressure exceeding rated pressure of 3 unit
Plugging of 4 oil separation core
Fault host malfunction of 5 contactor fault host
